new and useful Improvements in a Printing.

Press, of which the following is a specification.

This invention relates to ne.7 and useful improvements in printingpresses.

@ne object of the invention is to provide an attachment for a printingpress of thc'cylinder type whereby the paper, as unwound from theordinary roll, may be printed into sheets and cut for binding or foldincThe chief` advantage of the attachment if is in the fact that it may bereadily applied to a simple form of printingI press now commonly usedfor printing sheets which have been previously cut and when so applied`the press will accomplish the same work which now requires the complexand expensive presses in use in printing newspapers and the like.

Another object of the invention is to provide an attachment for printingpl sses of the cylider or printing roller type, which will give thepress much greater capacity, will require less labor to operate, andwill make it possible to use paper which is put up in rolls rather thanpaper which is cut into sheets. thus resulting in economy in that thepaper in rolls is considerably1 cheaper than that which is outintosheets previous to printin lVith the above and other objects inview1 the invention has particular relation to certain novel features ofconstruction. operation and arrangement of parts, au erimple of which isgiven in this specification and illustrated in the accompanyingdrawings, wherein Figure 1 is a fragmentary side elevation of a printingpress, showing the attachment, partially in section, applied' thereto.

Referring now more particularly to the drawings, wherein lile numeralsof reference designate similar parts in each of the figures, the numerall designates the side members of the press frame, which stand upvertically and are spaced apart. letween these side members, in thefront of the frame, there is a horizontal type plate 2 ylhis type plateis reciprocated baclr and forth in the usual manner through theconventional re ciprocating mechanism, which has not been shown, as itis common to printing presses and familiar to those versed in the art ofprinting. Integral with the side members 1, and upstending` therefrom,are the standards 4i, .lprovided with aligned bearings wherein the shaft5 is rotatably mounted. Fixed upon this shaft. between the standards,there is a printing roller or drum (i. rlhis drum has the cams 7, 7 oneat each end, provided for a purpose to be hereinafter stated. Thenumerals 8 and 9 refer to the upper and lower paper rolls, which arecarried upon the respective shafts 10 and 11, 100 which have endbearings in the frame 1Q. The shaft is driven. by a suitable belt 13,which operates over a pulley fixed on the shaft 10, and the shaft 11 isdriven by means of a suitable cross belt 14, which operates over thepulleys 15 and 16. which are fixed drum 6 and returning over the rollers19 and 20. These supporting rollers have end bearings in the frame ofthe press, and are driven by a suitable belting, as shown in Figure 6,the roller 1T rotating; backwardly with respect 'to the directionottravel of the paper so as to give the required tension to the paper asbeing printed. The tixedrod 18 and the rollers 1T, 19 and 20 have theadjustable edge guides 21v 21 thereon, between which the sheet of paperpasses and which may be adjusted to accommodate sheets oit differentwidths. Co-operating with the rollers 17 and 2O are the tension rollers22 and 23, which are supported bythe arms 24 and 25, pivotally mountedon the trameworlr, and these tension rollers assist in ,friving therequired tension to the sheet as it passes through the press. There istransverse shaft 26 having` end bearings inthe opposite sides of thetrame-worlnand iixed to the opposite ends ot this shaft, are bellcranks, ea ch having,` 'the short arm 2'?" and the long depending,` arm28. Pivoted to the treo end of each short arm 27. there is a push rod29, having a long slot 30'tnrough which the pin 31, carried by thetrame-work, projects. The pull spring 32 is attached at one end to thepin and at its other end to the push rod above the pin. The 'free end oteach push rod 29 has a roller bearing 33, which rides upon theadjustable cam 34, which fixed upon the shatt 5. `lProjectingfyupwardlytrom the shaft 26, there is abracliet 35. This bracket 35supports the clamp 36, adapted to clamp the paper between it and the-rod18, as will be hereinafter referred to. The push bars 37 vare provided,one on each side. These bars are pivoted at one end to the long;` arm28, and at their other ends theyv are pivoted to the lock-bars 39 by`means otV the pins 38; These lock-bars are arranged to move lengthwisein the bearings 40, carried by and forming part of the trame-work, andunderneath said bearings, are the guides 41 in which the ends of t-hetransverse drag' bars 42 and 43 travel. Fastened to the respective endsof these bars are the brackets 44, 44. which move in said guides, andpins 45 :ar-l ried bythe bar 43 pass through bearingsl in the bar 42.and surrounding` said pins 45,7and

interposed betweenthe bars 42 Aand 43 are the coil springs 46, 46. which'l'orin resilient seats for the bar 42. The long bearing1s40 vand theguides 41, underneath are connected.

`bv the sleeves 47, 47, which are formed integrally therewith, andwithin the respective y, euides 41.',there are the lock bars 48 whichhave the integral latches 49, 49 projecting up throuffh the" sleeves 47,and whose tree ends are beveled, and normally project intocorrespondingly shaped notches` 50 in the underside of the bar 39. The'inner endet each ot the bars 39 has a roller bea-ring 51 1n rollingcontact with the ends ot the druinar 6 and actuated, at times, by thecams 7, there-A 01"". Pull springs 52 are attached at one end to theunderside ot the bearing 49, and at their other ends to the` loclrbars48, and which tend to hold the latches 49 seated in the notches 50. Thesheet oi? paper passes between the drag' bars 42 and 43and is atintervals clamped between them, tor a purp ose to behereinaitterstated.` V I j Pivoted to the sides et lthe type plate 3 at its linnerend, are the shift arms 51, 51, whose free ends are vmpti'urired andprovided with the adjustingI bolts 52', 52.rwhich are threaded throughisaid upturned/ends. The

inner ends of the bolts' have swivel connections with the adjustingblocks 53, These varms aretied together by means of the tie bars 54 and55, the latterl of which rests upon" the flat springs 56, 56 projecting`out trom the adj acent end of the type plate, thus providing' ayielda-ble support for the shift arms. As the press plate moves inwardlyinto printing relation with the roller 6,\aldjusting" bolts 57, 57contact `against the lower drag' bar 43 andtorce the said drag harsalong', to advance the sheet ot paper being printed in synchronismwiththe pressiplate and print ing roller. These adjusting bolts arethreaded through the lugs 58, 58, upstanding from the respectivearms51,\151. Previousto the movement of the drag,- bars, however, they arecaused to grip the sheet of paper by the cam 34 contacting against theroller 33 and forcing the push rod 29 upwardly, which operates throughthe bell cranks, to which said push rod isvpivoted, to impart a thrustto the push bars 37. and these drive the lookin?,- bars 39 along' intheir .bearings 40 against the beveled ends of the latches 49, j

forcing;` the same downwardly and driving l are in position to contact'against the rollers Y 51, and hold the drap` bars in clamped positionuntil the printing operation is complete-and the type plate is ready tostart backwardly and thereupon the cams 7 release said rollers 5 1. Theopposite ends of the bearings 40 have the plugs 60 screwed therein, andinterposed between thesel plugs i and. the corresponding' lock-bars, arethe j uushsprinpgsl, whiclrthen force said lockbarsbackwardly untilthenotches 50 align with the latches 49, whereupon the springs 52 i liftthe lock-bars 48 from contact with the studs 59, and the .dra-g` bar 42is thereupon raised out of contact with the sheet of paper by thesprings 46. As the type plate returns,

lessees the blocks Contact against said drag bars and return them totheir,` original position. The 1ange ot movement ot said'drag barema-ybe varied by a suitable adjustment ot the bolts 52 and 57. rhe cam maybeadjusted through the instrumentality oi the set screw j 62 so that thedrag barsvwill clamp the paper at the desired time. i

-The printing roller G is driven through ay series of gears, shown in`Figure 1P. In this ligure the numerai designates a transverse driveshaft rotatablyvv mounted in 'the trame work and one end ot whichcarries the belt pulley 6d. Fixed upon the shaft 63 there is a smallspur gear which is in mesh with a larger spur gear 66, which is linedupon the transverse shaft 67, and this gear is in mesh with and drives alarger gear wheel 68, which is liXed upon the shaft Fixed upon the endof shaft 5, opposite the cam 34, there is a cam 69 provided to actuatethe shears, hereinafter described.

While one side of the sheet is being printed,

the shears do not operate and the sheet ci paper is unwound from theroller 8 and wound on the roller 9. Vhile printing the other side of thesheet, these rollers are reversed and the paper is unwound from saidlast mentioned roller and passes through the press to print the otherside ot the sheet. As the other side oi' the sheet is printed, it is cutinto sections for folding, by means ot' said shears. rllhese shearsinclude the fixed transverse blade 70, whose ends are secured to thestandards 71, 71, and the reciprocating blade 7 2, mounted above theiiXed blade. One end ci2 the reciprocating' blade 7 2 is pivoted to oneof the standards 71, and at itsl other end works in a guide 7 8 carriedby the upper end of the other standard. A shear actuating lever 74 ispivoted at one end to theblade 72. This lever is tulcrumed at anintermediate point on the bolt 7 5 which may be adjusted vertically inthe slot 76, through which it passes, so as to carry the tree end of'the lever 74 into, or out or' contact with the cam 69. When the sheet isbeing printed on one side, the lever 74 is adjusted out ot Contact withsaid cam, and the shears do not operate. When the rolls are reversed andthe other side of the sheet is printed, the lever 74 is adjusted so thatthe cam 69 will contact therewith and operate the shea-rs. The sheet asnow printed, will pass along between said blades, which are actuatedthrough the mechanism described, to cut the sheet into proper sections,which tall down upon the. receiving platform 77, or onto a suitablefolding machine, (not shown). It will be necessary to so adjust thesheet that the shears will cut through the blanlr space left between thepages, rather than through the printing. For this purpose I haveprovided an adjusting roller 7 8, whose ends are mounted in the longtransverse bearings 79 ot the tramefworlr. This roller may be, adjustedto any desired position relative to the sheet of paper, and thereby thesheet may be so adjusted relative to the shears, that it will be cut atthe required place.

.Provision is made for varying thel range ot' movement ot' the drag barsft2 and 43, so

that pages or sections otldiilerent sizes may be printed.I This isaccomplished through the Iin,strumentality,otf suitable cams as 80,which are secured 'to the respective bars Si, arranged on eachsideot-the Jframe. rllhese cams are secured to said bars by means oit thebolts 82, which pass through said cams and through the oblongslot 83 insaid hars 81. The arms 51 carry the respective rollers 88, S3, arrangedto contact against the underside of the cams-80, and thereby the arms 5lwill be pressed downwardly so that the adjusting bolts 57 will bedisengaged from the drag bars i3 at the proper time and the advancementot the sheet thereby stopped. 1t is obvious that the cams 8O may beadjusted to any desired position, and the range ot movement ont the dragbars thus' varied in accordance with the length of the printed sectionof the sheet.

What I claim is l. In a printing press, a clamping device arranged toclamp the sheet of paper passing around the lprinting roller, and holdthe same stationary, drag bars adapted to intermittently clamp andrelease said sheet to advance the same and a mechanism arranged torelease said clamp and simultaneously actuate the drag bars intoengagement with the sheet of paper.
